The term ‘refractory metal’ is used to describe a group of metal elements that have exceptionally high melting points and are resistant to wear, corrosion, and deformation.
Industrial uses of the term refractory metal most often refer to five commonly used elements:
Molybdenum (Mo)
Niobium (Nb)
Rhenium (Re)
Tantalum (Ta)
Tungsten (W)
The identifying feature of refractory metals is their resistance to heat. The five industrial refractory metals all have melting points in excess of 3632°F (2000°C).
Introduction The glass manufacturing industry is boosting with a market of 106.44 billion dollars in 2021[1], and millions of tons of glass are produced every day using molybdenum electrodes and other agents. Here, we are going to focus on glass melting and the molybdenum electrodes it employs. Hope that you can have a better understanding […]

What Is Thermal Conductivity? Thermal conductivity (denoted by k, λ, or κ) refers to a material’s ability to conduct heat at specific temperature and pressure, and it is measured in W/m•K (watts per meter-Kelvin). Highly thermally conductive materials are used to make heat sinks. Materials that transfer heat slowly act as excellent insulators. Different materials […]

1. Introduction to Alloys An alloy is a blend of 2 or more chemical elements, one of which is supposed to be a metal. Different substances of controlled amount are added to a metal to form alloys with desirable properties. Examples of alloys like stainless steel, bronze, and brass are applied to various fields including […]

Refractory metals are metallic elements of the periodic table with unique properties such as extremely high melting points. However, they can remain solid at room temperature. These characteristics make these materials ideal for research-based and critical nuclear reactions. What Are Refractory Metals? Refractory metals possess a melting point above 2,000° Celsius (3,632° F) and are […]

Metals are made up of atoms that are composed of electrons held in orbit by the pull of the nucleus. When exposed to light, metals give off energy, this phenomenon is referred to as the photoelectric effect. The light has to be of a certain frequency for this to be effective. This means that the […]
